Description
Technical Field
[0001]
The present invention relates to an ammonia manufacturing
apparatus and an ammonia manufacturing method using renewable
energy.
Background Art
[0002]
Conventionally, as a technique for converting renewable
energy into an energy carrier, a technique for manufacturing
hydrogen (H 2 ) by electrolysis of water using electric power
generated by renewable energy has been proposed. For example,
Patent Literature 1 describes that when hydrogen is generated by
electrolysis using renewable energy, out of electric power
generated by a power generation device, electric power consumed
when an electrolytic device performs electrolysis is supplied on
a priority basis, and surplus electric power is supplied for
transportation and storage of hydrogen.
[0003]
However, hydrogen has a low boiling point, is not easily
liquefied, and has problems in transportation, storage, and the
like. A compound containing many hydrogen atoms (H) in a
molecule thereof, such as ammonia, methane, or an organic
hydride has been proposed as an energy carrier. In particular,
ammonia (NH3 ) is attracting attention because ammonia can be burned directly and does not emit carbon dioxide (C02) even if ammonia is burned.
[0004]
Electrolysis requires a relatively large amount of
electric power. When power is generated in a suitable place
where renewable energy is easily available and ammonia is
manufactured using hydrogen manufactured by electrolysis,
transportation and storage are possible by using ammonia as an
energy carrier. However, since renewable energy uses natural
energy, the power generation amount thereof is liable to
fluctuate. Patent Literature 1 describes that surplus electric
power of renewable energy is supplied to an external device such
as a hydrogen booster, but neither describes nor suggests that
shortage of electric power is supplemented in a case of shortage
of the power generation amount of renewable energy.

Advantageous Effects of Invention
[0020]
According to the first aspect, a raw material component
for ammonia synthesis is used as an energy storage medium, and
when surplus electric power is generated from renewable energy,
pressure energy can be stored in the raw material component. In
a case of shortage of electric power from renewable energy, the
stored pressure energy can be converted into motive power to
generate power.
As a result, surplus and shortage of electric power due to
renewable energy can be effectively dealt with. In addition,
renewable energy can be used as a power source for electrolysis that generates hydrogen from water.
[00211
According to the second aspect, by storing the surplus
electric power of the first power source using renewable energy
as the pressure energy of the raw material component, surplus
and shortage of electric power due to renewable energy can be
more effectively dealt with.
[0022]
According to the third aspect, by using nitrogen which can
be easily stored and boosted by liquefaction as an energy
storage medium, surplus and shortage of electric power due to
renewable energy can be more effectively dealt with.
[0023]
According to the fourth aspect, since the surplus electric
power of the variable renewable energy can be converted into
pressure energy of an energy storage medium and stored, surplus
and shortage of electric power due to the variable renewable
energy can be more effectively dealt with.
[0024]
According to the fifth aspect, the first power source
using renewable energy can be included as a power generation
facility involved in ammonia synthesis.
[0025]
According to the sixth aspect, when electric power
obtained by the power generation facility using renewable energy
is consumed for electrolysis of water, shortage of electric
power is less likely to occur and the operating ratio of a water electrolytic device can be increased.
[00261
According to the seventh aspect, a part of the power
source for electrolysis of water depends on a power source other
than the first power source, and the first power source using
renewable energy can be used as a power source of the balance.
[0027]
According to the eighth aspect, electric power obtained by
the surplus electric power processing unit can be used by any
one of the hydrogen generation unit, the nitrogen supply unit,
the ammonia synthesis unit, and the surplus electric power
processing unit.
[0028]
According to the ninth aspect, a raw material component
for ammonia synthesis is used as an energy storage medium, and
when surplus electric power is generated from renewable energy,
pressure energy can be stored in the raw material component. In
a case of shortage of electric power from renewable energy, the
stored pressure energy can be converted into motive power to
generate power. As a result, surplus and shortage of electric
power due to renewable energy can be effectively dealt with. In
addition, renewable energy can be used as a power source for
electrolysis that generates hydrogen from water.
[0029]
According to the tenth aspect, by storing the surplus
electric power of the first power source using renewable energy
as the pressure energy of the raw material component, surplus and shortage of electric power due to renewable energy can be more effectively dealt with.
[00301
According to the eleventh aspect, by using at least a part
of the pressure-reduced raw material component after the raw
material component is used for power generation in the surplus
electric power processing unit for ammonia synthesis, the raw
material component can be effectively used.
[0031]
According to the twelfth aspect, by storing at least a
part of the pressure-reduced raw material component after the
raw material component is used for power generation in the
surplus electric power processing unit, the raw material
component can be effectively used. The eleventh and twelfth
aspects can be combined with each other such that a part of the
pressure-reduced raw material component is used for ammonia
synthesis and the other part is stored.
[0032]
According to the thirteenth aspect, electric power
obtained by the surplus electric power processing unit can be
used by any one of the hydrogen generation unit, the nitrogen
supply unit, the ammonia synthesis unit, and the surplus
electric power processing unit.

Description of Embodiments
[0034]
Fig. 1 is a flow chart illustrating an outline of an
ammonia manufacturing apparatus and an ammonia manufacturing
method of the present embodiment. An ammonia manufacturing
apparatus 100 of the present embodiment includes: a hydrogen
generation unit 12 that generates hydrogen by electrolysis of
water; an ammonia synthesis unit 15 that synthesizes ammonia by
a reaction between hydrogen and nitrogen using hydrogen
generated in the hydrogen generation unit 12; and a nitrogen
supply unit 20 that supplies nitrogen to the ammonia synthesis
unit 15. The hydrogen generation unit 12 includes a water
electrolytic device 12A that electrolyzes water.
[0035]
The ammonia manufacturing method of the present embodiment
includes: a hydrogen generation step of generating hydrogen by
electrolysis of water; an ammonia synthesis step of synthesizing ammonia by a reaction between hydrogen and nitrogen using hydrogen generated in the hydrogen generation step; and a nitrogen supply step of supplying nitrogen to the ammonia synthesis step. The hydrogen generation unit 12, the ammonia synthesis unit 15, and the nitrogen supply unit 20 can be used in the hydrogen generation step, the ammonia synthesis step, and the nitrogen supply step, respectively.
[00361
As a power source for the water electrolytic device 12A, a
first power source 101 using renewable energy is used. The first
power source 101 is derived from electric power generated by a
power generation facility 11 using renewable energy. The power
generation facility 11 may be installed as a part of the ammonia
manufacturing apparatus 100. The power generation facility 11
may be installed by an electric power company different from an
installer of the ammonia manufacturing apparatus 100.
[0037]
The power generation facility 11 may be installed
exclusively for the ammonia manufacturing apparatus 100, or may
be used for a joint purpose of a demand of the ammonia
manufacturing apparatus 100 and other demands. The installation
location of the power generation facility 11 may be on the same
site as the ammonia manufacturing apparatus 100, may be a
location adjacent to the ammonia manufacturing apparatus 100, or
may be a location away from the ammonia manufacturing apparatus
100.
[00381
As the first power source 101, variable renewable energy
selected from solar power generation, wind power generation,
solar thermal power generation, and ocean power generation may
be used. As the first power source 101, non-variable renewable
energy such as biomass power generation, geothermal power
generation, or hydropower generation may be used. In either
case, renewable energy can be used as the power source for the
water electrolytic device 12A.
[00391
Note that the ocean power generation is not particularly
limited, but examples thereof include wave power generation
using wave energy, tidal flow power generation using a
horizontal flow due to tide, tidal force power generation using
a tide level difference due to tide, ocean flow power generation
due to horizontal circulation of seawater, and ocean temperature
difference power generation due to a temperature difference
between a surface layer of the ocean and the deep sea. The
hydropower generation may be a canal type or a dam type, or a
dam canal type in which both are used in combination.
[0040]
Electric power consumption of the electrolysis of water in
the hydrogen generation unit 12 corresponds to electric power
consumption of the water electrolytic device 12A. Rated power
generation output of the power generation facility 11 is
preferably larger than the electric power consumption of the
water electrolytic device 12A. As a result, when electric power obtained by the power generation facility 11 is supplied to the water electrolytic device 12A, shortage of electric power is less likely to occur and the operating ratio of the water electrolytic device can be increased. As the power source for the water electrolytic device 12A, it is also possible to use only the first power source 101 without using a third power source 103 described later.
[0041]
First electric power consumption, which is a part of the
electric power consumption of the water electrolytic device 12A,
may be derived from the third power source 103, which is a power
source other than the first power source 101. As the third power
source 103, a power source due to power generation other than
renewable energy can be used. Examples of the power generation
other than renewable energy include thermal power generation and
nuclear power generation.
[0042]
The third power source 103 may be used in a case of
shortage of electric power supplied from the first power source
101 with respect to the electric power consumption of the water
electrolytic device 12A. In addition, the first electric power
consumption may be set to a certain ratio in advance, and the
third power source 103 may be used constantly. When the electric
power consumption of the water electrolytic device 12A is 100%
is, the ratio of the first electric power consumption is, for
example, 10 to 90%, but may be less than 10%, and may be larger
than 90%.
[00431
Second electric power consumption, which is the balance of
the electric power consumption of the water electrolytic device
12A with respect to the first electric power consumption
described above, is preferably derived from the first power
source 101. In this case, the rated power generation output of
the power generation facility 11 is preferably larger than the
second electric power consumption. As a result, when electric
power obtained by the power generation facility 11 is supplied
to the water electrolytic device 12A, shortage of electric power
is less likely to occur. When the electric power consumption of
the water electrolytic device 12A is 100% is, the ratio of the
second electric power consumption is, for example, 10 to 90%,
but may be less than 10%, and may be larger than 90%.
[0044]
When the electric power consumption of the water
electrolytic device 12A is compared with the rated power
generation output of the power generation facility 11, rated
electric power consumption of the water electrolytic device 12A
may be compared with the rated power generation output of the
power generation facility 11. During operation of the ammonia
manufacturing apparatus 100, the electric power consumption of
the water electrolytic device 12A may be different from the
rated electric power consumption.
[0045]
The ammonia manufacturing apparatus 100 of the present
embodiment includes an energy carrier manufacturing unit 10 for converting renewable energy into ammonia, which is an energy carrier. The energy carrier manufacturing unit 10 may include a combination of the power generation facility 11, the hydrogen generation unit 12, a low-pressure hydrogen transfer unit 13, a low-pressure hydrogen storage unit 14, the ammonia synthesis unit 15, and an ammonia storage unit 16, or a part thereof.
[0046]
Hydrogen (H2) generated in the hydrogen generation unit 12
is set so as to have a pressure suitable for storage in the low
pressure hydrogen transfer unit 13, and can be stored in the
low-pressure hydrogen storage unit 14. The low-pressure hydrogen
transfer unit 13 may include a hydrogen booster. The hydrogen
storage pressure in the low-pressure hydrogen storage unit 14
is, for example, 80 bar (8 MPa).
[0047]
The ammonia synthesis unit 15 receives hydrogen and
nitrogen and synthesizes ammonia (NH3 ) by a catalytic reaction.
Hydrogen as an ammonia synthesis raw material may be directly
supplied from the hydrogen generation unit 12, but is preferably
supplied from the low-pressure hydrogen storage unit 14 to the
ammonia synthesis unit 15. Nitrogen as an ammonia synthesis raw
material is supplied from the nitrogen supply unit 20 to the
ammonia synthesis unit 15. Ammonia synthesized in the ammonia
synthesis unit 15 may be stored in the ammonia storage unit 16.
[0048]
The nitrogen supply unit 20 may include a liquid nitrogen
manufacturing unit 21 that manufactures liquid nitrogen from air. Examples of the liquid nitrogen manufacturing unit 21 include a device that liquefies air by compression and separates liquid nitrogen by fractional distillation of the liquefied air.
Liquid nitrogen manufactured in the liquid nitrogen
manufacturing unit 21 is stored in the liquid nitrogen storage
unit 22. When the nitrogen supply unit 20 includes the liquid
nitrogen manufacturing unit 21, desired nitrogen gas can be
obtained from the atmosphere. When the nitrogen supply unit 20
includes the liquid nitrogen storage unit 22, nitrogen can be
stored in a liquefied state in a saving space.
[0049]
The nitrogen supply unit 20 may include a nitrogen gas
generation unit 23 that vaporizes liquid nitrogen (LN2 ) stored in
the liquid nitrogen storage unit 22 into nitrogen gas (GN 2 ). The
nitrogen gas generation unit 23 may generate nitrogen gas
according to the amount supplied to the ammonia synthesis unit
15. The nitrogen gas generation unit 23 is not limited to a
device that receives liquid nitrogen and generates nitrogen gas
by vaporization thereof, but may be a device that separates
nitrogen from air in the gas phase by adsorption of oxygen
molecules or the like and supplies high-purity nitrogen gas. The
nitrogen gas generation unit 23 may be a device that supplies
nitrogen gas from a facility that stores required nitrogen gas.
[0050]
The ammonia manufacturing apparatus 100 of the present
embodiment includes a surplus electric power processing unit 30,
using hydrogen or nitrogen, which is a raw material component of ammonia, as an energy storage medium. The first surplus electric power processing unit 30 uses hydrogen generated in the hydrogen generation unit 12 as an energy storage medium. The second surplus electric power processing unit 40 uses nitrogen supplied from the nitrogen supply unit 20 as an energy storage medium. The ammonia manufacturing apparatus 100 may include both the first surplus electric power processing unit 30 and the second surplus electric power processing unit 40, or may include only one of the first surplus electric power processing unit 30 and the second surplus electric power processing unit 40.
[0051]
By storing a raw material component (hydrogen, nitrogen)
supplied to the ammonia synthesis unit 15 at a higher pressure
in the surplus electric power processing unit 30, 40 using
surplus electric power of renewable energy power generation, the
surplus electric power can be converted into pressure energy of
the raw material component and stored. Furthermore, by
converting the pressure energy of the raw material component
stored at a higher pressure into motive power, power can be
generated. As a result, energy derived from the surplus electric
power can be used as electric energy in a case of shortage of
electric power from renewable energy. An expander 34, 45 can
generate power by driving a turbine or the like when high
pressure gas is expanded.
[0052]
The first surplus electric power processing unit 30
includes: a high-pressure hydrogen transfer unit 31 that includes a hydrogen booster 32, boosts hydrogen from the low pressure hydrogen storage unit 14, and transfers the hydrogen to the high-pressure hydrogen storage unit 33; and the first expander 34 that converts pressure energy of hydrogen supplied from the high-pressure hydrogen storage unit 33 into motive power to generate power. The high-pressure hydrogen transfer unit 31 in the illustrated example includes the hydrogen booster
32 and a pipe 31A that transfers hydrogen boosted by the
hydrogen booster 32 to the high-pressure hydrogen storage unit
33. When the hydrogen booster 32 boosts hydrogen gas, the
hydrogen gas is compressed and the volume of the high-pressure
hydrogen gas is reduced. The hydrogen booster 32 in this case
is, for example, a hydrogen gas compressor.
[00531
The second surplus electric power processing unit 40
includes: a liquid nitrogen transfer unit 41 that includes a
liquid nitrogen pump 42, boosts nitrogen from the liquid
nitrogen storage unit 22, and transfers the nitrogen to a high
pressure liquid nitrogen storage unit 43; a vaporizer 44 that
vaporizes liquid nitrogen supplied from the high-pressure liquid
nitrogen storage unit 43; and the second expander 45 that
converts pressure energy of the nitrogen gas vaporized by the
vaporizer 44 into motive power to generate power. The liquid
nitrogen transfer unit 41 in the illustrated example includes
the liquid nitrogen pump 42 and a pipe 41A that transfers
nitrogen boosted by the liquid nitrogen pump 42 to the high
pressure liquid nitrogen storage unit 43.
[00541
The low-pressure hydrogen storage unit 14 and the liquid
nitrogen storage unit 22 are raw material component storage
units for storing a raw material component (hydrogen, nitrogen)
supplied to the ammonia synthesis unit 15. Meanwhile, the high
pressure hydrogen storage unit 33 and the high-pressure liquid
nitrogen storage unit 43 are high-pressure raw material
component storage units that store a raw material component
(hydrogen, nitrogen) as an energy storage medium at a higher
pressure than the raw material component storage unit.
[0055]
The second surplus electric power processing unit 40 in
the illustrated example stores liquid nitrogen at a pressure
higher than that of liquid nitrogen stored in the liquid
nitrogen storage unit 22 in the high-pressure liquid nitrogen
storage unit 43. Therefore, when high-pressure liquid nitrogen
stored in the high-pressure liquid nitrogen storage unit 43 is
supplied to the second expander 45, the high-pressure liquid
nitrogen needs to pass through the vaporizer 44.
[0056]
When a raw material component supplied to the ammonia
synthesis unit 15 is stored as nitrogen gas, nitrogen gas at a
higher pressure may be stored as an energy storage medium. In
this case, although not particularly illustrated, the second
surplus electric power processing unit 40 includes a high
pressure nitrogen gas transfer unit that includes a nitrogen gas
booster, boosts nitrogen gas from a low-pressure nitrogen gas storage unit, and transfers the nitrogen gas to a high-pressure nitrogen gas storage unit. As a result, high-pressure nitrogen gas supplied from the high-pressure nitrogen gas storage unit can be directly supplied to the second expander 45 to generate power. That is, when high-pressure nitrogen gas is used as an energy storage medium, the vaporizer 44 can be omitted, and the second expander 45 can convert pressure energy of nitrogen gas supplied from the high-pressure nitrogen gas storage unit into motive power to generate power. When the nitrogen gas booster boosts nitrogen gas, the nitrogen gas is compressed and the volume of the high-pressure nitrogen gas is reduced. The nitrogen gas booster in this case is, for example, a nitrogen gas compressor.
[0057]
Fig. 2 illustrates a step of storing high-pressure
hydrogen using surplus electric power 35. Fig. 3 illustrates a
step of obtaining electric power 36 by power generation using
high-pressure hydrogen. Fig. 4 illustrates a step of storing
high-pressure nitrogen using surplus electric power 46. Fig. 5
illustrates a step of obtaining electric power 47 by power
generation using high-pressure nitrogen.
[0058]
In order to store an energy storage medium in the high
pressure hydrogen storage unit 33 or the high-pressure liquid
nitrogen storage unit 43, it is necessary to convert a raw
material component into a high-pressure energy storage medium.
The high-pressure hydrogen transfer unit 31 and the liquid nitrogen transfer unit 41 are high-pressure raw material component transfer units for transferring a high-pressure raw material component. The surplus electric power 35, 46 is used as a motive power source for the high-pressure raw material component transfer unit. Specifically, the surplus electric power 35 is used as a motive power source for the hydrogen booster 32, and the surplus electric power 46 is used as a motive power source for the liquid nitrogen pump 42. As a result, the surplus electric power can be effectively utilized.
[00591
The surplus electric power 35, 46, which is a motive power
source for the high-pressure raw material component transfer
unit, is at least one selected from the group consisting of
surplus electric power 101A of the first power source 101 and
surplus electric power 102A of the second power source 102. The
surplus electric power 101A of the first power source 101
corresponds to electric power obtained by subtracting rated
electric power consumption of the water electrolytic device 12A
from electric power supplied by the first power source 101. The
surplus electric power 102A of the second power source 102 may
be surplus electric power generated by any power source
different from the first power source 101.
[00601
The surplus electric power 101A of the first power source
101 is generated when electric power supplied by the first power
source 101 exceeds rated electric power consumption of the water
electrolytic device 12A. Therefore, when the power generation amount by the power generation facility 11 increases, the surplus electric power 101A may be generated. Furthermore, when the first power source 101 is a common power source for supplying electric power to a plurality of consumers, the surplus electric power 101A may also be generated, for example, when electric power consumption of other consumers is low. In either case, it is not appropriate to supply electric power exceeding rated electric power consumption to the water electrolytic device 12A. Therefore, the surplus electric power
101A is used as a motive power source for the high-pressure raw
material component transfer unit.
[0061]
The second power source 102 may be a power source using
renewable energy or a power source using power generation other
than renewable energy, and a power source using renewable energy
and a power source using power generation other than renewable
energy may be used in combination. Renewable energy used for the
second power source 102 may be variable renewable energy
selected from solar power generation, wind power generation,
solar thermal power generation, and ocean power generation, and
may be non-variable renewable energy such as biomass power
generation, geothermal power generation, or hydropower
generation. Examples of power generation other than renewable
energy used in the second power source 102 include thermal power
generation and nuclear power generation. The second power source
102 may be any power source other than the first power source
101, and two or more types of power sources other than the first power source 101 may be arbitrarily combined with each other.
[00621
The surplus electric power 102A of the second power source
102 may be surplus electric power derived from a power source
not serving as a power source for the water electrolytic device
12A. The second power source 102 may be system electric power
supplied from another power generation company through an
electric power system. The surplus electric power 102A of the
second power source 102 in this case corresponds to system
electric power when a "raised demand response" for increasing
electric power consumption is demanded in response to a request
of a power generation company. This case contributes to
stabilization of electric power supply of the power generation
company, and therefore it is possible to further reduce electric
power supply cost.
[0063]
When the surplus electric power 101A, 102A can be used
from the first power source 101 or the second power source 102,
at least a part of the surplus electric power 101A, 102A can be
used as the surplus electric power 35, 46 serving as a motive
power source for the high-pressure raw material component
transfer unit, and a high-pressure raw material component can be
stored. As illustrated in Fig. 2, high-pressure hydrogen may be
stored in the high-pressure hydrogen storage unit 33. As
illustrated in Fig. 4, high-pressure liquid nitrogen may be
stored in the high-pressure liquid nitrogen storage unit 43.
Storage of high-pressure hydrogen and storage of high-pressure liquid nitrogen may be performed at the same time.
[00641
In a case of shortage of electric power from renewable
energy, as illustrated in Fig. 3, the electric power 36 may be
generated by the first expander 34 using high-pressure hydrogen
in the high-pressure hydrogen storage unit 33 for use. As
illustrated in Fig. 5, the electric power 47 may be generated by
the second expander 45 using high-pressure liquid nitrogen in
the high-pressure liquid nitrogen storage unit 43 for use. Power
generation of the first expander 34 and power generation of the
second expander 45 may be performed at the same time.
[0065]
The electric power 36, 47 generated by the expanders 34,
can be supplied to any one or more of the hydrogen generation
unit 12, the nitrogen supply unit 20, the ammonia synthesis unit
, and the surplus electric power processing unit 30, 40. In
addition, the electric power 36, 47 may be used for any electric
power demand of the ammonia manufacturing apparatus 100 or
facilities related thereto. Use of the electric power 36, 47 is
not particularly limited, but examples thereof include
electrolysis, motive power, control, communication, lighting,
display, heating, cooling, pressurization, decompression, and
air conditioning.
[00661
At least a part of a raw material component (hydrogen,
nitrogen) after being used for power generation by the expander
34, 45 may be supplied to the ammonia synthesis unit 15 and directly used for ammonia synthesis. At least a part of the raw material component (hydrogen, nitrogen) after being used for power generation by the expander 34, 45 may be stored in the raw material component storage unit. As a result, the raw material component can be effectively used. At least a part of the raw material component (particularly nitrogen gas) after being used for power generation by the expander 34, 45 can be released into the atmosphere and discarded.
[0067]
According to the above-described ammonia manufacturing
apparatus 100, a raw material component for ammonia synthesis is
used as an energy storage medium in the surplus electric power
processing unit 30, 40, and when the surplus electric power 35,
46 is generated from renewable energy, pressure energy can be
stored in the raw material component. In a case of shortage of
electric power from renewable energy, the pressure energy of the
raw material component stored at a high pressure can be
converted into motive power to generate power. By using these
together, it is possible to effectively deal with surplus and
shortage of electric power due to renewable energy.
[0068]
At least a part of the surplus electric power 35, 46
serving as a motive power source for the high-pressure raw
material component transfer unit is preferably the surplus
electric power 101A of the first power source 101, and more
preferably the surplus electric power 101A of the first power
source 101 using variable renewable energy. As a result, there is little influence by output fluctuation of renewable energy used as a power source of the water electrolytic device 12A, and effective use is possible.
[00691
At least a part of the surplus electric power 35, 46
serving as a motive power source for the high-pressure raw
material component transfer unit is preferably the surplus
electric power 102A of the second power source 102 using
renewable energy, and more preferably the surplus electric power
102A of the second power source 102 using variable renewable
energy. As a result, surplus electric power generated in power
generation of renewable energy can be effectively used. Note
that as at least a part of a motive power source for the high
pressure raw material component transfer unit, electric power
other than surplus electric power may be used in addition to the
surplus electric power 35, 46
